ICE-PAN SIGNAL.

Application filed September 13, 1921.

To all whom it may concern:

Be it known that I, GEORGE H. Bonn- KnMrnR, a citizen of the United States, and a resident-of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Ice-Pan Signal, of which the following is a full, clear, and exact description.

This invention relates to an ice pan sig nal, and has for an object the provision of a simple, compact, rugged device which can be readily attached as a unit to an ice pan or other similar receptacle to cause the giving of an alarm when the liquid level within the pan or receptacle reaches a predetermined value.

Another object resides in the provision of means whereby the operation of this device is made certain and substantially accurate under all conditions and whereby a definite, clearly audible signal results.

A further object resides in the provision of means whereby a plurality of signals are successively given as the water within the receptacle rises.

A still further object resides in the construction and arrangement of parts whereby the'whole signal device can be attached to a pan merely by clamping or sliding the sig nal support over the edge of the pan or receptacle.

Another object resides in the particular construction and arrangement of parts which are hereinafter described and claimed and shown in the accompanying drawings.

The invention is illustrated in the drawings, of which- Figure 1 is a partial plan view of a receptacle or pan showing the device attached to the edge thereof;

Figure 2 is a side elevation; and

Figure 3 is a section taken on the line 33 of Figure 1.

The invention as shown in the drawings comprises a float which is pivoted to a slip port adapted to be slipped over the edge of This float is connected to a cam' the pan. element with which a signal device is adapted to co-operate so that in accordance with the movement of the float the cam element moves and causes an actuation or a plurality of actuations of the signal device whereby an alarm is given.

As shown more specifically in the draw- Specification of Letters Patent.

ings, the device is adapted to be applied to a pan or receptacle 1 and comprises a mounting or support in the form of a plate of sheet material or metal having an outer face 2 adapted to lie along the outer edge of the receptacle and an inner face 3 adapted to lie along the inner edge of the receptacle. This mounting or support may be made of any suitable material, such as sheet iron or steel, and along the lower portion of this outer face 2 is provided with a turned-in flange or lip t to provide the necessary gripping action of the body of the receptacle 1 between the inner and outer portions 2 and 8 of the support. This support is made of one piece of metal which is bent over, as at 5, and rests upon the top of the edge of the receptacle 1. The support, as shown in Fig. 1, is properly curved to conform to the curvature of the receptacle.

On the inner face 8 of this support I fasten a suitable stub shaft, such as 6. This stub shaft 6 may be connected to the support in any suitable manner, such as by soldering, welding or riveting. To this stub shaft 6 an arm 7 is pivoted. On the outer end of the arm is provided a float 8 of any suitable form or construction. To another portion of the support I suitably connect in any desired. manner a bearing member 9, preferably in the form of a hollow tube, adapted to support a cam element 10. This cam element is mounted on a pin 11 which extends into the bearing member 9. This cam element 10 is in the form of a fiat plate having a plurality of notches such as 12 therein. These notches are formed between the curved walls of the cam element 10 and are arranged in a predetermined succession angularly along the periphery of the member 10. A link 13 connects the arm 7 with a portion of the cam member 10.

I have also provided a bell clapper 14 mounted on an arm 15, a portion of which is coiled in the form of a spring 16. This arm 15 beyond the spring 16 extends through a hollow tube 17 suitably connected to the top edge 5 of the support. The outer end of this arm 15 extends, as at 18, over the edge of the cam element 10 and is adapted to bear thereon. It will be seen from Fig. 2 that the weight of the clapper l twill tend normally to cause the end portion 18 of the arm 15 to bear against the edge of the cam element 10. 'On the opposite face 2 of the mounting I provide a bell 19 suitably supported on the stub shaft 20. I

In the operation of the device, as the float 8 moves. in accordance with the level of the liquid within the receptacle 1, its connection with the cam element 10 will cause the movement of the cam element to such a point that the end 18' of arm will drop 7 give the bell 19 a sharp blow.

will be further enhanced.

into the first notch. .When this'action takes place, the bell clapper 14 will drop and The resilience of the spring portion 16 will cause the clapper to be immediately retracted from the bell so that the clarity of the blow Further movement of the cam element 10 will cause the portion 18 of the arm 15 to ride up on the curved wall of the first notch 12 until it is in position to drop into the second notch, whereupon a similar action takes place. A succession of notches 12 is provided so that a plurality of signals are given before the level of the liquid gets to a point where it is liable to spill over the edge of the receptacle.

It will be observed that this device and the operating partsthereof are all mounted on the supporting plates '2 and 3 which are integrally connected, and that this mechanism can be attached for use toany'receptacle merely by slipping the mounting or support over the edge of the receptacle, and

can be as simply and quickly removed there from.
